Startings were several and in different times and on different topics in psychology, as webinars were not many and they passed in different intervals of time. Initially, the test was the launch on one type of audience - a wide, but several double groups, to get into the best layer of people. After a small optimization in the work remained only the best groups, for which the budget was later optimized.
The last launch was a little different, the hypothesis was tested to divide people by professions and co-operate after optimization on the best groups.
